Just substitute each number in for the variables: 9 for m and 3 for n.
2m+2n
= 2(9)+2(3)
= 18+6
= 24
The answer is 72
You would have to add sixty-five plus seven
Nine plus a unknown number equals unknown.
Answer:A
Step-by-step explanation:
-8=a(2+5)^2 + 41
-8=a x 7^2 + 41
-8=a x 7 x 7 +41
-8=49a+41
Collect like terms
-8-41=49a
-49=49a
Divide both sides by 49
-49/49=49a/49
-1=a
a=-1
